When Windows is starting, pressing the Shift key can allow you to bypass programs loading during startup. Some malware, such as the UZA O/S worm, disables this feature. Here's how to re-enable the use of a shift override when Windows is loading. Note: These steps require editing the System Registry (REGEDIT). For tips on using REGEDIT, see the Windows System Registry Tutorial.
Difficulty: Easy
Time Required: 2 minutes
Here's How:
- Click Start
- Click Run
- Type REGEDIT
- Click OK
- Browse to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon - Click once on the winlogon key in the left pane to highlight it.
- In the right pane, look for the value "ShiftOveride"
- Right click the value "ShiftOveride" and select Delete
- Click File | Exit to exit the Registry Editor.
